SAN ITARY DRIN KIN G-FOUNTAIN Application filed March 15, 1919.

To all whom it may 0012/ em:

Be it known that I, WILLIAM G. JACKSON, a citizen of the United States, residing at Richmond, in the county of Contra Costa and State of California, have invented new and useful Improvements in Sanitary Drinking-Fountains, of which the following is a specification.

The present invention relates to improvements in sanitary drinking fountains. The object of the invention is to provide a drinking fountain of such construction as to entirely avoid the possibility of disease germs being transmitted thereby from one drinker to a succeeding drinker at the same fountain.

In the accompanyin drawing, Figure 1 is a longitudinal vertica section of one form of my improved drinking fountain; Fig. 2 is a cross-section thereof on the line 2-2 of Fig. 1; Fig. 3 is a vertical section of another form thereof; Fig. 4 is a similar view of a cap used therein.

Referring to the drawing, 1 indicates a horizontally extending supply pipe controlled by a valve 2 and communicating with any suitable source of supply; said pipe passes through an end of a bowl 3 and dis charges through its open end within said bowl with such force and direction that the discharged water impinges upon the under side of the top 4 at the end of the bowl remote from that at which it is discharged. Said stream is then deflected downward and flows along the curved bottom of the bowl, escaping through the drain outlet 6. The sides of the bowl converge downward and said outlet is preferably located at the lowest part of the meeting line of said con vergent sides. Said bowl at the top overhangs the discharge end of the pipe 1, but the opening at the topof the bowl is sufliciently wide to permit the drinker to turn his face sidewise toward the discharge pipe to catch the stream of water flowing therefrom.

The walls of the bowl are recessed, as shown at 7, opposite to the highest portion of the stream of water to facilitate the inser- Specification of Letters Patent.

tion therebetween of the face of the drinker and the turning of his face sidewise in order to catch the stream in his mouth. This enables the bowl to be much smaller than it would have to be without these recesses, in which case the bowl would have to be sufficiently large to receive the whole face of the drinker.

In the form of the invention shown in Fig. 3, the supply pipe 8 connects with two branches, 9, leading therefrom in opposite directions, said branch pipes 9 then curving upwardly and back on themselves, and the open or discharge ends of said branch pipes are so directed that the branch streams 11 of water issuing therefrom meet at an angle which is slightly less than two right angles, with the result that said streams unite in an upwardly flowing common stream 12. This stream flows upwardly through a central hole in a removable cover or cap 13, which completely covers the discharge ends of the said branch pipes, so that no saliva from the mouth of the drinker can fall on said discharge ends to be subsequently washed off by the water and carried into the mouth of the succeeding drinker.

I claim In a sanitary drinking fountain, in combination with a supply pipe discharging water obliquely upward, a bowl into one end of which the discharge pipe enters, the portion of the bowl opposite the discharge pipe being sufiiciently inclosed to retain the water issuing from the discharge pipe and impinging thereagainst, the portions of the walls of the bowl between which is the highest point of the stream of water issuing from said discharge pipe being recessed from the upper edge downward to facilitate drinking from said stream, said recessed portions being sufficiently remote from said discharge pipe to prevent saliva from the mouth of a drinker dropping on to a part of said pipe accessible to the issuing stream of water.
